43.1: A New 42-in. AC PDP Using MAoD II Driving Scheme

We present a new prototype 42″PDP using Samsung SDIs MAoD II driving scheme (Multiple Addressing with Overlapping Display period) suited for a high-resolution PDP. We used the commercial driver ICs to implement the entire parts of driving system and achieved the luminance of 600 cd/m2 with a single scan addressing method with the advantage of space charge priming. It also adopted 14 sub-fields in order to reduce the dynamic false contour.

A MgF2/MgO multiple protecting layer in ac plasma-display panels

A MgF 2 /MgO multiple protecting layer coated on a MgO layer in ac plasma-display panels (AC-PDPs) was developed to obtain high brightness and low driving voltages. The material characteristics of this layer were examined by carefully changing the deposition conditions, and the display characteristics of AC-PDPs using this protecting layer were studied. It was demonstrated that this new method is effective in lowering the firing and sustaining voltages of PDPs and enhancing the brightness of the panel as well.

Coating protecting layers in alternating current-plasma display panels

Two protecting layers, a MgF2/MgO multilayer coated MgO layer and a LaF3 layer coated MgO layer, were studied in order to overcome the weakness of the conventional MgO protecting layer for use in color alternating current (ac) plasma display panels (PDPs). The material characteristics of these protecting layers were examined by carefully changing the growing conditions. The display characteristics were also examined by manufacturing real PDPs using these protecting layers. These two protecting layers had higher secondary electron-emission yields than conventional MgO. It was demonstrated that these two methods were effective for lowering the firing and sustaining voltage of PDPs and also for enhancing the brightness of the panel.

Address‐While‐Display technique combined with gas‐discharge AND logic for driving AC‐PDPs

— A hybrid AWD/AND drive technique has been developed in which an Address-While-Display (AWD) scheme is combined with an AND logic characteristic that gas discharges demonstrate. The AWD technique enables AC-PDPs to be driven at high luminance, while the AND logic reduces the number of scan drivers by an order of magnitude. A detailed analysis of the addressing operation has been made. The hybrid drive utilizes the AND logic in two ways: (1) a combination of two voltage pulses and (2) a combination of a voltage pulse and discharge-priming particles. It was found that the addressing operation requires the establishment of a discharge between the scan and data electrodes, and also between the scan and display electrodes.
